1601: Inline snapshots for tests r=matklad a=theotherphil
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/1127.
The "cargo format" commits are required to get the formatting tests to pass. However, they actually mess up the formatting.

1606: Add `if let`, `while let` and match arm inlay hints r=matklad a=SomeoneToIgnore

Add more inline hints support.
Looks like `while let` type inference support is missing currently, so the corresponding hint tests lack the actual results.
I've also could not find a good way to distinguish between `a` and `b` pats in the following expressions:
`if let Some(Test { a: None, b: y }) = &test {};`
In this case we don't need to add a hint for first pat (`a: None`), since it's matched against the particular enum variant and need a hint for `y`, since it's a new variable.
But both `a` and `b` are `BIND_PAT` with similar contents, so looks like there's nothing I can check for to find any differences.
I don't display any hints for such cases now, to avoid confusion, but would be nice to know if there's a way to fix this behavior.

1549: Show type lenses for the resolved let bindings r=matklad a=SomeoneToIgnore
Types that are fully unresolved are not displayed:

A few concerns that I have about the current implementation:
* I've adjusted the `file_structure` API method to return the information about the `let` bindings.
Although it works fine, I have a feeling that adding a new API method would be the better way.
But this requires some prior discussion, so I've decided to go for an easy way with an MVP.
Would be nice to hear your suggestions.
* There's a hardcoded `{undersolved}` check that I was forced to use, since the method that resolves types returns a `String`.
Is there a better typed API I can use? This will help, for instance, to add an action to the type lenses that will allow us to navigate to the type.
